Modes — pillow-heif 1.4.0 documentation

# Modes

Possible `mode` modes are:

> - `BGRA;16` or `BGRa;16`

> - `BGR;16`

> - `RGBA;16` or `RGBa;16`

> - `RGB;16`

> - `L;16`

> - `LA;16`

> - `I;16`

> - `I;16L`

> - `BGRA` or `BGRa`

> - `BGR`

> - `RGBA` or `RGBa`

> - `RGB`

> - `LA`

> - `L`

Note

By default `convert_hdr_to_8bit` parameter in `open_heif` is `True` so all images will be opened as a 8 bit ones. To open images in BGR mode, set `bgr_mode` to True in `open_heif/read_heif`.

Starting from 0.11.2 version you can set `hdr_to_16bit` to False in `open_heif/read_heif` to get 10/12 bit images without bits shifted to 16 bit. Those will be RGB(A);10(12), BGR(A);10(12) modes instead of RGB(A);16, BGR(A);16.

When saving image from Pillow to HEIF format, next modes will be converted automatically before encoding:

> - `P` with transparency will be converted to `RGBA`

> - `P` will be converted to `RGB`

> - `I` will be converted to `I;16L`

> - `1` will be converted to `L`

> - `CMYK` will be converted to `RGBA`
